Key features of the V2 Receiver include: - 5 independent channels. - Adjustable tone control. - Volume control. - Vibrate Mode on/off. - Excellent range (100m+ in ideal conditions). To make sure that your receiver stays in tip top condition it is important to look after it and treat it with care. To ensure the greatest reliability and longevity: - Clean and thoroughly dry the item off before storing it in a dry place. - We recommend keeping it somewhere warm (or at least stable temperatures) to avoid heating and cooling that may cause condensation. - If you're putting it away for extended periods of time we strongly recommend taking out the batteries. Battery leaks are not covered by the ATT warranty.
